Short description
Morfologia | Morfometria
Spine dorsali (totale): 9; Raggi dorsali molli (totale): 13-14; Spine anali 3; Raggi anali molli: 14 - 15. Pectoral filaments 3; fin membranes uniformly brown like all other fins. Vomer lacks deciduous tooth plates on both sides throughout its life history. Posterior part of maxilla shallow, 2-3% of SL. Long tooth plate extension onto lateral surface of lower jaw, 9-10% SL (Ref. 41639).
Too small to be of major commercial importance (Ref. 57343).

Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00332 - 0.01511), b=3.09 (2.91 - 3.27), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic Level (Ref.
69278): 3.6 ±0.4 se; Based on size and trophs of closest relatives
Resilienza (Ref.
69278): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Vulnerability (Ref.
59153): Low vulnerability (21 of 100) .
